近年由於疫情的影響之下，使得無線通訊的要求也被越來越重視，讓大多數的人對於高速且低延遲的產品也有所增加，而壓控振盪器(Voltage-controlled Oscillator , VCO)為了要提供穩定的訊號讓他在無線收發機系統中成為不可或缺的存在。本篇論文總共設計兩顆晶片並將目標朝5G系統的毫米波方向進行設計，本篇設計為採用台灣積體電路製造公司(Taiwan Semiconductor Manufacturing Company , tsmc) 0.18 µm 1P6M CMOS 製程進行模擬與晶片製作
本論文中所設計的第一顆電路為應用於5 G系統毫米波雙推式式低雜訊壓控振盪器。操作頻率在25.89 GHz至28.05 GHz。並使用一組MOS對將輸出功率提高至-3.7dBm。核心消耗功率為8.48mW。在載波頻率1MHz處的相位雜訊為
-108.67dBc/Hz。
本論文中所設計的第二顆電路為使用電容耦合技術之28GHz低相位雜訊雙推式壓控振盪器設計。操作頻率在27.5 GHz至29.76 GHz。使用擬態電組讓核心功耗有下降，使電路核心消耗功率為4.62mW。在離載波頻率1MHz偏移處的相位雜訊-109.03dBc/Hz。

In recent years, due to the impact of the pandemic, the demand for wireless communication has been increasingly emphasized. Most people also have an increased demand for high-speed and low-latency products. The voltage controlled oscillators (VCOs) are indispensable components in wireless transceiver systems that needs to provide stable signals. Thesis paper designs a total of two chips and aims to target the millimeter-wave direction of 5G systems, and the design is simulated and manufactured using tsmc 0.18 µm 1P6M CMOS process.
The first circuit designed in thesis paper is a push-push low noise VCO for millimeter-wave 5G systems. The oscillation frequency is from 25.89 to 25.05 GHz, and a MOS pair is used to increase the output power to -3.7dBm. The core power consumption is 8.48mW. The phase noise is -108.67dBc/Hz at 1MHz offset frequency.
The second circuit designed in this paper is a 28 GHz low phase noise push-push VCO using capacitive coupling technology. The oscillation frequency is from 27.5 to 29.76 GHz. The core power consumption is reduced to 4.62mW by using a pseudo resistance. The phase noise is -109.03dBc/Hz at the carrier frequency of 1MHz.
